From: andy at andyh dot co dot uk Operating system: n/a PHP version: 5.0.2 PHP Bug Type: Documentation problem Bug description: imagettftext 'text' parameter wrongly describes Unicode character entities
Description: ------------ The description of the 'text' parameter in imagettftext wrongly describes decimal numeric character entities as "UTF-8 character sequences", whereas the function actually accepts BOTH of UTF-8 character sequences, and decimal numeric character entities. http://uk2.php.net/imagettftext " text The text string. May include any UTF-8 character sequences (of the form: {) to access characters in a font beyond the first 255 " { is not a UTF-8 character sequence, it is a decimal numeric character reference as per section 5.3.1 of HTML 4.0.1. http://www.w3.org/TR/html4/charset.html#h-5.3.1 This has nothing to do with the UTF-8 encoding of Unicode characters; the reference is entirely ASCII, and the character it refers to is the code point in the Unicode character set - not the corresponding UTF-8 encoding of that character. Also the example value "123" given is not past the first 255 characters in the font. imagettftext passes the string to GD, which expects a UTF-8 encoded string according to its documentation. So, any character above 127 will be a malformed UTF-8 string. See: http://www.boutell.com/gd/manual2.0.33.html#gdImageStringFT " The null-terminated string argument is considered to be encoded via the UTF_8 standard; also, HTML entities are supported, including decimal, hexadecimal, and named entities (2.0.26). " Given characters in the 128-255 range, which are not valid UTF-8 single byte characters, it appears to fall back to using them as a single-byte character, but this is not documented. Suggest the description be changed to something like: " text The text string, encoded in UTF-8. May include decimal numeric character references (of the form: €) to access characters in a font beyond position 127.
